西太平洋斑马珊瑚 Oulastrea Crisata（Scleractinia：Faviidae）的形态变异。动物学研究 50(1)：43-52。珊瑚在热带和亚热带的各个纬度生长，这些地区的环境因素（包括年平均温度以及水体透明度和温度的季节变化）差异很大。这些环境因素可能导致珊瑚骨骼形态的纬度变化。在这项研究中，研究了斑马珊瑚 Oulastrea crepata 的形态变化，这是一种具有黑白隔膜、群落直径通常小于 10 厘米的小型珊瑚物种。此前的研究表明，卷叶藻可以在极端环境条件下生存，例如低温和浑水。从泰国到日本，跨越热带、亚热带和温带地区，收集了 100 个卷曲 O. crepata 菌落。使用单变量和多变量分析测量和检查了珊瑚石的五个微观特征。测量的所有微观特征在纬度区域之间存在显着差异（嵌套方差分析，p < 0.05）。典型判别分析（CDA）表明，珊瑚岩直径是导致 3 个纬度区域中 O.crispata 变化的最重要特征，尽管第一和第二个典型变量的图显示来自不同纬度区域的 O.crispata 不能完全分开。然而，检测到 CDA 组质心之间的马哈拉诺比斯距离存在显着差异，这表明西太平洋卷叶螟形态变异存在纬度梯度。 http://zoolstud.sinica.edu.tw/Journals/50.1/43.pdf
of morphological variations in zebra coral Oulastrea crispata (Scleractinia: Faviidae) in the West Pacific. Zoological Studies 50(1): 43-52. Corals grow across latitudes throughout the tropics and subtropics where environmental factors, including the average annual temperature and seasonal changes in water clarity and temperature, substantially vary. These environmental factors could lead to latitudinal variations in coral skeletal morphology. In this study, morphometric variations of the zebra coral Oulastrea crispata, a small coral species with black and white septa and a colony diameter usually < 10 cm, were investigated. Previous studies reported that O. crispata can survive in extreme environmental conditions, such as low temperatures and turbid water. One hundred colonies of O. crispata were collected from sites spanning Thailand to Japan, across tropical, subtropical, and temperate regions. Five micro-characters of corallites were measured and examined using univariate and multivariate analyses. All micro-characters measured significantly differed among latitudinal regions (nested ANOVA, p < 0.05). A canonical discriminant analysis (CDA) indicated that corallite diameter was the most important character contributing to variations in O. crispata among the 3 latitudinal regions, although a plot of the 1st and 2nd canonical variables showed that O. crispata from different latitudinal regions could not be fully separated. Nevertheless, significant differences in the Mahalanobis distances between the CDA group centroids were detected, suggesting a latitudinal gradient of morphological variations in O. crispata in the West Pacific. http://zoolstud.sinica.edu.tw/Journals/50.1/43.pdf
